Fukushima Soil Contamination Probed

AmiMoJo writes "New research has found that radioactive material in parts of north-eastern Japan exceeds levels considered safe for farming. The findings provide the first comprehensive estimates of contamination across Japan following the nuclear accident in 2011. An international team of researchers took measurements of the radioactive element caesium-137 in soil and grass from all but one of Japan's 47 regions. The researchers estimate that caesium-137 levels close to the nuclear plant were eight times the safety limit, while neighbouring regions were just under this limit."

    A huge earthquake and a tsunami both well above the level the plant was designed to withstand and it took it, with just some slight explosions and making great swathes of land uninhabitable for generations.

    Nuclear power ftw!

    Lets not forget the reactor up the coastline that took just as big of a hit..and came out relatively unscathed because someone took the time and knowledge to build it higher than sea level in a country prone to Tsunami.

    Poor Engineering FTW!

    The study seems to be based on few actual measurements, it is mostly a modeling of how the material spread. Additional measurements are needed in the areas where the model predicted high dosage.

      The exciting(?) thing about this study though is how small of an area is contaminated beyond the legal limit. Since Cs is the major radionuclide that was released then these mappings should also be closely correlated to background doses. Given the conservative estimates that are used for setting regulations I am even more convinced that the general Japanese public is in essentially no danger from the radiation. I would like to see a more detailed analysis of the area right around the plant but given the picture in the article it gives me hope.

      Many in the anti-nuclear crowd like to spout off and say that Fukushima has rendered vast amounts of land unusable for generations. This news actually bodes well for the Japanese people that in a couple of years all the land that was previously not part of the power generating stations might be returned to original state.

    The only thing that surprises me is that someone seriously came out with a study prior to this one saying the soil was A-OK after what happened.

    Of course, if you read TFA, you find that the legal limits are only exceeded in the area immediately around the plant, and that everywhere else it's fine.

    In other words, we have this exclusion zone. And we shouldn't be farming there....

  5. Not good for farming, but perfect for gardening by sandytaru · · Score: 5, Interesting

    Although the land won't be suitable for farming for many years, botanists already know how to accelerate the cleanup by using plants that soak up radiation and contamination like sponges (phytoremediation.) Such contamination studies have been done at several major universities (including my own local one, which cleaned up an area that had been contaminated with non radioactive mercury within one year.) The question is whether Japan will swallow its pride and have its farmland turned into short term radioactive gardens.

    Except the earthquake is not what caused the problems. The generators that were shut down by flood waters, effectively killing the cooling system, causing overheating and eventually meltdown, Did.
